Answer:
1/4
Explanation:
DNA replication is semi-conservative, which means that during this process one DNA strand will be from the original DNA template, whereas the other DNA strand will be newly synthesized. In the first round of DNA replication, daughter cells receive a DNA molecule containing one original DNA strand and one newly-synthesized DNA strand (in this case, one of these daughter cells will contain a mismatch). If the mismatch is not repaired, then in the second round of replication the DNA molecule containing the mismatch would separate during replication, and the DNA strand containing the erroneous nucleotide will serve as a template for the synthesis of a new DNA molecule, thereby producing a permanent mutation.

human beings are also natural resources,so by me operating this computer,am utilizing myself as a natural resource.
The laptop is a device which is generally used. It is composed of electrical conductors which contains metals such as copper. Copper is a natural resource.
What are Natural resources?Natural resources are those resources which are drawn from the nature and are used with few modifications. This includes the sources of valued characteristics such as those for commercial and industrial use, aesthetic value, scientific interest, and cultural value.
Copper is a highly recyclable, non-renewable natural resource. It is present in a finite amount and cannot be regenerated once used fully. Copper is a soft and malleable metal which is used in the electrical wires and cables for its good conductivity, in the industrial machinery and construction materials for its durability, machinability, and corrosion resistance, and also the ability to be cast with high precision.

‘Plant and animals are interdependent on each other’, Why do they depend on each other. Write three points to justify your answer.
Answer:
Animals are consumers and they all depend on plants for survival. Some eat plants directly, while others eat animals that eat the plants. In turn, some plants depend on animals to help spread their seed. Decomposing animal carcasses can also provide nutrients for plants to grow.
Plants and animals depend upon each other as mutual interdependence is must for their survival. Plants provide shelter for animals and they make oxygen for the animals to live. When animals die they decompose and become natural fertilizer plants. Plants depend on animals for nutrients, pollination and seed dispersal
how is sound recorded
Answer:
Sound is made up of waves in the form of vibrations in the air. Or you can use the signal to record the sound on magnetic tape. This works by a similar process of moving a magnet, but that magnet causes a magnetic tape to gain magnetization in patterns that represent the sound.
In a digital recording system, sound is stored and manipulated as a stream of discrete numbers, each number representing the air pressure at a particular time. The numbers are generated by a microphone connected to a circuit called an ANALOG TO DIGITAL CONVERTER, or ADC.
hope this helps
have a good day :)
Explanation:
Answer:
sound is made up of waves in the form of vibrations in the air, and can be detected by the human ear. Using magnets analoque technology takes sound waves and turns them into electrical pulses. When a metal conductor is moved inside the magnetic field an electric current is produced in that wire.

balance the following chemical equation making sure to apply the principle of the law of conservation of mass
Answer:
2Zn+ 4HCl=2ZnCl2 +2H2
CH4+2O2=CO2+2H2O
Fe + 3NaBr=FeBr3+3Na
The balanced chemical equations are given below:
[tex]Zn + 2HCl[/tex] → [tex]ZnCl_2[/tex] + H2. [tex]CH_4 + 2O_2[/tex] → [tex]CO_2 + 2H_2O[/tex]. [tex]Fe + 3NaBr[/tex] → [tex]FeBr_3 + 3Na[/tex]. What do you mean by Chemical equation?Chemical equations may be defined as an illustration of a chemical reaction by using symbols and the amount of substance used in the reactant to form a desirable product.
In the first reaction, two atoms of hydrogen are there on the product side while only one is there is the reactant side, so to balance them, you put 2HCl, the reaction is balanced now.
In the second reaction, four atoms of hydrogen are there on the reactant side while only two are on the product side, so to balance them you put 2H2O on the product side, now balance the oxygen atom and put 2O2 on the reactant side. The reaction is balanced now.
In the third reaction, bromine has three atoms on the product side, to balance them you need to put 3NaBr on the reactant side, now to balance sodium atoms put 3Na on the product side. The reaction is now balanced now.
The principle of the law of conservation of mass states that mass is neither be created nor destroyed in chemical reactions.
Therefore, the balanced chemical reactions are described above.

light-dependent reactions and fermentation
I need help
Answer:
Krebs cycle and electron transport chain
Explanation:
Energy in form of ATP, which is needed by all living cells, is produced from a cell process called CELLULAR RESPIRATION. Cellular respiration is composed of three other processes depending on the availability of oxygen: glycolysis, Krebs cycle and electron transport chain.
Overall, glycolysis which takes place in the cytoplasm produces 2 molecules of ATP while the Krebs cycle and electron transport chain (ETC) produces a collective accumulation of 34 ATP molecules.
select the true statement about dehydration synthesis or hydrolysis
1.) during hydrolysis, an enzyme joins two water molecules, producing polymer
2.) during dehydration synthesis a water molecule breaks apart two monomers
3.) during dehydration synthesis and enzyme joins two monomers water is a byproduct
4.) during hydrolysis, a monomer breaks apart into two polymers,water as a byproduct
The true statement is that during dehydration synthesis, an enzyme joins two monomers and water is a byproduct.
WHAT IS DEHYDRATION SYNTHESIS:
Dehydration synthesis is a reaction that involves the joining together of two or more smaller molecules to form a much larger and complex molecule accompanied by the release of water (H20). During dehydration synthesis, the hydrogen (H) of one monomer combines with the hydroxyl group (OH) of another monomer releasing a molecule of water.An example of dehydration synthesis is the reaction of glucose molecules to form larger polysaccharides.

What makes human beings different from other animals?
Answer:
There are many characteristics in humans that can define us to be different than other animals. For example, our body. Humans are generally more flexible than animals. One can bend in different ways while other animals are minimalistic in comparison to our flexibility. Another example is our life span. Humans have more life span than most animals but not all. Many animals have lesser life span from days, months to few years with exception of tortoise, elephants which have more than ourselves. Like I said in the beginning, there are many more traits that differ us from other animals.
